[RFC3261], as amended by [RFC3853], provides a mechanism for end-to- end encryption and integrity using Secure/Multipurpose Internet Mail Extensions (S/MIME) [RFC5751]. Several security properties of [RFC3261] depend on S/MIME, and yet it has not been widely deployed. One reason is the complexity of providing a reasonable certificate distribution infrastructure.

 Certificate Management Service for the Session Initiation Protocol (SIP)


   This document defines a credential service that allows Session    Initiation Protocol (SIP) User Agents (UAs) to use a SIP event    package to discover the certificates of other users.  This mechanism    allows User Agents that want to contact a given Address-of-Record    (AOR) to retrieve that AOR's certificate by subscribing to the    credential service, which returns an authenticated response    containing that certificate.  The credential service also allows    users to store and retrieve their own certificates and private keys.
